Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Celigo

Prices are not published on any of the three editions
Billed on endpoints and flows, so the cost is driven by how many systems you connect rather than by volume through them
API Builder, lookup caching and a sandbox all require the Professional edition
Single sign-on is optional on Standard and included from Professional up
Unlimited endpoints and the full governance features are Enterprise only

Windmill

Free self-hosted tier caps SSO users at 10 and workspaces at 3, requiring Enterprise for larger teams.
Compute unit and seat-based pricing (developer vs. operator seats, worker compute units) adds pricing complexity beyond a flat monthly fee.
Email triggers are capped at 100/day on the free tier, limiting event-driven use cases without upgrading.
Smaller ecosystem of pre-built integrations compared to more established automation tools like n8n.
